From the introduction:
Down on your luck you’re offered a simple task of guarding a contingent of clerics on a holy visit to an archaeological site for research. What begins as a change to recoup your losses and regain your strength soon becomes an exercise to outwit and survive the challenges of the Temple of the Forgotten God.
Temple of the Forgotten God is a Dungeon and Dragons 3.5 adventure suitable for four – 5th level characters. The adventure is easily modified for both higher-level characters or different game systems with some minor modifications.
It is recommended that no character with flight ability (magical or non-magical) be in the party. The party must start with less than 5 G.P in coin and or viable treasure.
